Male repro tract Flashcards
Testes
gametes and hormones
epididymides
sperm maturation and transport
vas deferens
sperm transport
accessory sex glands
production of seminal plasma
pelvic urethra
semen transport
penis
copulatory organ and semen deposition
Bull
testis has vertical orientation and the tail of the epididymis is in the ventral position
Ram
testis has vertical orientation and the tail of the epididymis in the ventral position
Stallion
Testis in horizontal orientation
Tail of the epididymis in causal position
Boar
testis in oblique orientation
tail of epididymis in dorso-caudal position
Dog
testis in oblique orientation
tail of epididymis in dorso-caudal position
tom cat
similar orientation to dog but penis in same orientation
Scrotum
layers-skin, tunica darts, scrotal fascia (external and internal spermatic fascia)
vaginal tunics
layers of peritoneum
parietal layer of tunica vaginalis- lines scrotal sacs
visceral layer of tunica vaginalis- covers testis and part of epididymis
vaginal cavity
contains serous fluid between vaginal tunics to allow mobility
testis layers (superficial deep)
visceral layer of tunica vaginalis
tunica albuginea (capsule of testis)
seminiferous tubules
mediastinum testis (aka: hilum of testis)- efferent ductules, rate testis (network of tubules)
Bull layers
parietal vaginal tunic
visceral vaginal tunic
tunica albuginea
scrotal ligament
attaches the internal scrotal fascia to the external scrotal fascia and skin
proper ligament
attaches the testis to the tail of the epididymis
efferent ducts
functional connection between testis and epididymal duct
mediastinum
lobules present
ram prostate
disseminate prostate within pelvic urethra
boars
large bulbourethral gland
prostate gland
in all species
dog
no bulbourethral gland or vesicular gland
boar
no ampulla
stallion
all accessory sex glands
tom cat
no ampulla or vesicular glands
bull penis
fibroelastic penis and sigmoid flexure located caudal to scrotum
stallion penis
musculovascular penis with no sigmoid flexure
boar penis
fibroelastic penis with sigmoid flexure cranial to the scrotum
spiral penis
dog penis
musculovascular penis, no sigmoid flexure and Os penis
tom cat penis
has barbs with prostate and bulbourethral glands
penile spines
Ram penis
urethra process
alpaca
cartilaginous process
bull penis following intromission
goes from straight to spiraling of the glans penis during erection
sperm manufacturing
high speed manufacturing, finishing, then shipping off, final alterations and packaging, then the delivery system
